Re: Building Emacs on WSL

For the record,

Emacs 25.1 builds fine and runs fine under WSL providing you install all the required packages.

I used :

../emacs/configure --with-jpeg --with-xpm --with-tiff --with-rsvg --with-xml2 --with-gnutls --with-imagemagick --with-png=yes

and mobaxterm as an X server. Everything is ok. I could even load Spacemacs with its about 100 packages.

Emacs master fails with the same configuration. It fails bootstrapping:

(gdb) run --batch --load loadup bootstrap

Starting program: /mnt/d/Source/emacs/build-emacs-ubuntu/src/temacs --batch --load loadup bootstrap

I must admit that I don't know how to read what gdb is reporting.

Just for the record...

I adopted the workaround suggested in etc/PROBLEMS (and from the WEB [*]):

echo 0 | sudo tee /proc/sys/kernel/randomize_va_space

and with it I was able to build,

./autogen.sh

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe" LDFLAGS="-pipe" CC="gcc" ./configure --prefix=/opt/emacs --build=x86_64-pc-linux-gnu --without-x --with-gnutls=no --disable-acl

make -j3

Emacs25 from the following source packages:

emacs-25.1.90.tar.gz
emacs-25.1.tar.gz
emacs-emacs-25.tar.gz (2016-12-11 10:50"17, 467768f64ee109fe)

BUT NOT emacs-master.tar.gz from master whose build always hangs as I described (./temacs --batch... see below)

At least, now I have an Emacs build (noX) working inside WSL!

Ciao,
Angelo.

(I waited for almost an hour)

I tried with a master of a few days ago which surely build and works on
GNU/Linux Mint 18, Windows (MSYS2/MinGW64) and macOS.

Just out of curiosity...

Ciao,
Angelo.
